  2. Bleed the air. Start the engine and turn the steering wheel several times so that the fluid temperature rises to approximately 50~60°C (122~132°F)operating temperature.
  3. Increase the engine speed to 1,000 rpm.
  4. Close the shut-off valve of the special tool and measure the fluid pressure to confirm that it is within the standard value range.

    Standard value 

    Oil pump pressure

    Relief pressure :

    7.6~8.1 MPa (78~83 kg/cm, 1102~1175 psi

    CAUTION: Don't keep the shut-off valve on the pressure gauge closed for more than ten seconds.
  5. Remove the special tool and then tighten the pressure hose to the specified torque

    Tightening torque 

    55~69 Nm (550~690 kg.cm, 40.6~50.9 Lb. ft)

  6. Bleed the system.
